JOGGING MECHANISM.

l Application filed September 4, 192,6. Serial No. 133,559.

This invention relates to jogging mechanism for paper sheets or cardsand particularly to a sheet receiving attachment for a printing machine,which attachment may ybe so arranged that sheets fed from` the machineinto substantially the same position may be neatly and automaticallyarranged in a regular pile.

The object of the invention is to provide an eflicient and comparativelysimple jogging mechanism which will be cheap to construct. andsatisfactory in operation. A speciiic object is to provide an improvedjogger arranged to act on two adjacent edges of a pile of sheets toforce the other two adj acentv edges against respectivo abutments. Afurther object is to provide a jogger attachment for a rotary printingmachine which will be conveniently operated intermittently from the samesource of power kwhich operates the printing machine.

Other objects and features of the invention will Ybecome apparent fromthe following description relating to the accompanying drawings whereinI have shown my preferred form. VThe essential characteristics` will besummarized in the claims.

In the drawings, Fig. 1 is a side elevation of my jogging mechanismattached to a rotary printing machine, a portion of the printing machinebeing broken away to illustrate certain parts, Fig. 2 is a plan of thejogging mechanism proper, Fig. 3 shows a convenient mechanism by whichthe printing elements and jogger elements may be driven in timedrelation to each other, Fig. 4 is a cross sectional detail view takenalong the line 4-4 on Fig. 2, Fig. 5 is a similar detail viewv takenalong the line '5-5 on Fig. 2.

Briefly, the mechanism, as shown, comprises a platform arranged to beconveniently secured to the base frame structure, for

example, of a multigraph. The platformhas two normally stationaryupright plates against which the sheets are stacked, and

suitable linkage which is in turn connected to a cam follower contactingwith a cam controlled by the multigraph drum driving mechanism.

Referring in detail to the drawings, A represents the multigraph machineresting on a suitable horizontal base plate B, having supporting legs C.Such supporting legs are usually four in number (two being shown). The.multigraph machine has side frame members 1 in which is'journalled ashaft 2 for a printing form drum or segment carrier 3. A. form carryingsegment is shown as comprising an arcuate shell like member 4 secured tothe shaft by hooked spring plates 5, and maintained in definite positionby cross rods 6. The cooperating printing element, the impressionmember, is shown at 6 mounted on a shaft 7 carried by the side framemembers. rIhere are also shown paper feed rollers 8 and 9 and a paperejector roller 10'. These parts may all be driven by a belt 12 extendingupwardly from the driving wheel of a suitable motor (not shown) locatedon a platform (not shown) carried by the legs C. Such belt may drive apulley indicated by broken lines in Fig. S

at 13 rigid with a small spur gear 14. This gear drives a larger spurgear 15 meshing with an impression platen driving spur gear 16, and thegear 16 drives a large spur gear 17 rigid with the drum support 3. Thereare other gearsmeshing with or driven from the gears 16 and 17 vforoperating the paper feed and ejector rolls, 20 being the ejector rollgear, and 21 and 22 the paper feed gears.

Driven by a small spur gear 23, rigid with the gear 15 is a spur gear 25mounted rigidly on a shaft 26 journalled in the side portion of the baseframe B. This shaft is arranged to drive the jogging mechanism which Iwill now describe.

The jogger platform or paper support preferably comprises a rectangularfiatpiece of material, such as wood, indicated at 30, and which may beVattached to the multigraph supporting base by latch pins 31 (Fig. 2)secured in brackets 33 fastened near the front edge of the member 30.These pins are resiliently mounted in order that they may be manuallywithdrawn, and the ends ef thepins forced into openings 84 in ears 35gpne beingl shown in Fig. 1) on lthe hase. By thislnieans the platform'be' swung iii; or down at any desired angle and re`` tained'in place insuch position by a baillike memberI 36 secured as by straps 37 to theunder side of the platform and having its free. ends bent outwardly asat 3S to engage openings (not shown) positioned along the inner sides ofthe rear legs C.

As shown, the paper positioning plates, consist of a rear abutment platee0., adjustably secured to the platform 80, substantially centrallylocated with reference to the printing drum, another adustable sideabutment plate 4:1, Fig. 2, and two reciprocable plates 50 andv 60positioned opposite the platesv l1 and 40. The plate al has an uprightportion 4t2 and horizontal portion l/3 resting on the platform andarranged, as shown in Fig. 2, to be ecured as by bolts l5 in any pair ofa double series of openings e6 on the plat- `form. `When so secured theplate may be moved within definite limits by reason of slots la 1n theportion lf3, by simply loosening` the bolts. The plate Ll() may be similarly' mounted, for example by a bolt a, arranged to be placed in anyone of a series of openings 46 and a slot (not shown) in the horizontalportion of the plate for receiving the bolt.

The jogger mechanism includes the slidable plates 50 and 60, the plate50reciprocating laterally of the platform, and the plate 60 forwardly andrearwardly. rll`he mounting for the plate 50, as shown, comprises aslideway formed by a fiat plate 51 and having over-hanging strips 52secured thereto to form horizontal recessed guides on the bottom of theplatform. The platform has an opening therethrough extending alittlebeyond each end of the strips 52. The carriage for the jogger platecomprises a rectangular strip 53 embraced by the recesses ot theslideway, this strip carrying a filler member 54 surmounted by a strip55 having its edges overliano'ing the member 54. The overhanging edgesof the strip v55 forma guideway for a bracket 56 'showni-is haring anupwardly extending portion 5T secured to the jogger plate 50. By thismeans the bracket 56 may slide along the overhanging edges of the plate55 and be clamped into any desired posit-iony by a thumb screw 5f),4

which may engage the top of theplate There 1s a slideway for the plate60 which is somewhat similar to that of the plate 50 but, as shown,allowing for no adjustment, This is desirable since all the necessaryadjustments may be effected by the other three plates. This slidewaycomprises, a bent niember 6l slidably mounted in plates 62, bent toembrace the member 6l as shown` in Fig. The member 6l extends upwardlyaround the forward edge of the platform 30 as at 63 and has a verticalextension 64 to which the plate is secured.

To prevent the paper from getting under' the plates, any or all oftheplates may haveyon their lower sides lugs, such as'indicated for anyconvenient length, for example, as

shown in dotted lines in Fig. 2, there are slots Gti extending` acrossthe greater portieri of the platform,- these slots being common to boththe plates s2 and 50. By this means the paper is prevented from gettingunder the plates, as it always rests above the floors of the slots tit,the lugs bearing against the edges of the sheets to shove them along, inthe case of the reciprocating plates. The lugs on the normallystationary plates prevent the paper from being shoved under them by thereciprocating plates.

Means for simultaneously operating the two reciprocating platesconsists, as shown, of a bell crank ZO pivoted at 7lV to the lower sideof the platform, one arm of the bellV crank having a loose pinconnection at [2 with the sliding member 53. rlhe other arm i" 5 of thebell cranl; 70 may move back and forth in a strap '7st, secured to theplatform and overhanging the' end of the arm as a guide.` nterinediatelyof the Vends of the arm .75 is Vpivotally attached a link 8O connected`at one end as at 8l with the bent member Gl to which the plate 6G isattached.

To reciprocate the Abell crank 70, l have shown a link connected at oneend with a rock arm 86 on a rockshaft 87 secured in brackets 88 on theplatform, the end lof the rock shaftr opposite the rock arm 86 havinganother' rock arm 879 connected to a twopart cam follower 'supportinglink 90.` The link 90 as shown in F ig. 1 extends diagonally upwardly`and is slidably supported at its ,upA wardly extending end' by reasonof a slot 92 therein, embracingthe shaft 26. The slot support for thelink. 9() allows the platform to be swung up ordown as required and thelink 90 may be adjusted by reason of boltsV 9Gn each extendingthroughrespective.l holes and slots inthe'link parts,` to maintain thefollower in contact. with the cam for any position of thc'platform.

The link 90 is reciprocated by reason of a lam follower'roller 95mounted on the link which bears against a cam 96 rigid with the rockshaft 26.l The cam has a low point shown a flat surface QS on one sidethereof,

`which allows the link 9() to assume its rear- 53 to pull bothjoggerplates against the pa-` lll() per. A. suitable adjustment may beprovided between the shaft 26 and cam4 96 wherefore the jogging takesplace at the proper time relative to feeding the paper from the machine.Preferably this should be so arranged as determined bythe length of thesheet to be stacked, so that the jogging takes place a moment after thesheet comes to rest on the platform or pile of sheets.

In order to minimize shock to the machine and to provide for emergency,as in case some foreign matter should prevent the return of the joggerplates to normal position, I have shown resilient means interposed inthe connection between the cam and the hell crank which operates theslides. This resilient connection preferably comprises a` compressionspring 105 suitably retained on the link against outward movement by awasher and spring, indicated generally at 106, and bearing at its rearend against a slidable knob which in turn bears against an upturned lip10S on the bell crank. rlhe link has a similar knob 109 rigid therewithon the side of the lip opposite the slidable'knob 107. Both theseknobs/are shown as rounded to compensate for the tilting movement of thelink, relative to the ear 108.

It will be apparent that should foreign substances prevent the return ofeither of the plates 50 or 60 to normal position after jogging the paperthe mechanism will not be damaged, the cam actiony since that action insuch case will be simply to compress the spring 105, the button 109drawing away from the lip on the bell crank 70. Under normal conditionsthe spring is strong enough to hold the knob 107 snugly against the lip108 to insure the withdrawal of the plates after jogging.

To set the device for a given size of sheet, the operator first turnsthe multigraph drum to position the cam approximately as shown in Fig.1, so that the reciprocating plates are in their jogging position. Theplate 42 is then adjusted to such position that the sli-eet as fed fromthe machine just clears it. The plate 50 may then be brought toward theplate 12 with a little less space between them than the paper width inorder that at each `reciprocation of the jogger plates the stack will beslightly compressed. The plate d0 is then moved toward the plate60leaving space enough for the paper length. It will be noted that theplate 40 isr very narrow, hence it may pass between the plates e2 and 50in case very short sheets are to be stacked. f y

I have found the jogging mechanism made in accordance with the abovedisclosure to be very eective in stacking sheets and to be very easilyadjusted for a great range of sizes of rectilinear shapes. Furthermore,the device is very little likely to getV out of order and practicallyall the parts may be very easily reached for repairs or attention bysimply taking o the platform and inverting it. Y
